Embodiment Construction

[0039] figure 1 A block diagram illustrating an apparatus 1 for providing output values ​​with associated uncertainties for a flexible modular plant is shown. Although the invention will be described below in relation to a flexible modular factory, the invention is also applicable to flexible modular machines. The device 1 comprises an interface 11 connected to a plurality of modular entities 21-a to 2n-a, where n is an integer value greater than one. Modular entities 21-a to 2n-a are physical devices that can be combined during runtime. The modular entities 21-a to 2n-a may include wires, walls, pipes, machines, actuators and sensors. The modular entities 21-a to 2n-a are installed according to a particular arrangement that describes the manner in which the modular entities are connected to each other. The layout can change during runtime. For example, during runtime, new modular entities 21-a to 2n-a may be added or may be connected to already existing modular entities 2...

Abstract

The invention provides a method for providing an output value with associated uncertainty for a flexible modular plant or machine comprising an arrangement of modular entities (21-2n). The uncertainty information associated with the operation of the modular entities (21-2n) is assigned to a plurality of the modular entities (21-2n). Input values are provided based on the operation of the modular entities (21-2n). A calculation unit (12) calculates an output value based on the input value. A calculation unit (12) calculates an input value uncertainty for each input value based on the uncertainty information of the modular entities (21-2n). A calculation unit (12) calculates at least one output value uncertainty associated with the output value based on the propagation of the uncertainty and using the input value uncertainty. The output value and the at least one output value uncertainty are output.

Description

technical field [0001] The invention relates to a method and a device for providing output values ​​with associated uncertainties for a flexible modular plant or machine. Background technique [0002] A manufacturing plant based on modular entities is beneficial in terms of increased flexibility in plant layout, reduced safety concerns during construction of the modular plant, and easier modification and replacement of the modular entities. [0003] The modular entities or devices of such a flexible modular factory may include components such as wires, walls, pipes, machines, actuators and sensors. Modular entities are installed according to a specific arrangement that describes the manner in which the modular entities are connected to each other. [0004] Sensors measure physical and chemical properties and provide measurement data subject to measurement uncertainty. The degree and type of uncertainty may be specified in the documentation for the respective sensor and may...
